Open‐cage silsesquioxanes have lower crystallinity without diminishing the thermal stability than traditional closed‐cage silsesquioxanes. Two of the three siloxane groups of commercially available corner‐opened cage silsesquioxanes were selectively substituted, and the remaining one was functionalized for the mono‐methacrylate monomer. The resultant polymer formed a homogeneous and transparent film with high‐thermal stability.
